HAY-PRESS.

A SPECIFICATION forming part of Letters Patent` No. 524,771, datedAugust 21, 1894.

Apfiicauon fuea January 19,1894.. serial No. 497,371. (No model.)

T0 @ZZ whom it may con/cern:

Be it known that I, JAMES A. STOKELY, of Kansas City, Jackson county,Missouri, have invented certain new and useful Improvements inHay-Presses, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to that class of haypresses in which a plunger isreciprocatedto form a bale at each movement, and has for its primaryobject to produce a machine of this character wherein the full strokeand greatest power ofwthe plunger is obtained with the minimum movementof the lever; thus economizin g in time and labor by lessening thedistance'to he traveled by the draftanimal attached to the lever.

Other objects of the invention appear in the following description, andare pointed out par'- ticularly in the' appended claims.

Referring to the drawings which illustrate this invention: Figure 1. isa front side elevation of a hay-press constructed in accordance withmyinvention. Fig. 2. is a top plan view of the same. Fig. 3. is acentral vertical longitudinal section of the saine, showing the plungerin elevation'. Fig. 4. is a vertical transverse section, takenon theline wof Fig.` 3, and looking in the direction indicated bythe arrows.Fig. 5. is a detailed view of one of the guide-roller supportingbrackets.

In the lsaid drawingspa hay pressof the usual elongated rectangular formcomprises the top 1, the bottom 2, and the front and rear sides 3 and4,* respectively. These sides are skeleton in form, being' composed of aseries of metallicY strips or bars arranged or spaced so as to form thelongitudinal and parallel slots 5, the object of which is hereinafterexplained. A

The press comprises two baling-chambers, and is provided with twoopenings 6, in its top, through which the hay to be pressed isintroduced into the baling-chamber. These openings are provided with thehinged doors 7, which are alternately closed and opened during theoperation of the machine, as hereinafter referred to. Secured verticallyupon the top of the doors and outward of each dooropening, are brackets,8,' and journaled in the upper end of the same are grooved guide-pulleys9. A cord 10 is attached to each door 7 near its free margin andextending upwardly and outwardly over their respective guidepulleys 9,carry upon their outer ends the counterbalance weights l11. Theseweights are adapted to hold the doors 7 in an opened position, normally.In order that these weights 11 may be guided in theirmovements, thebrackets 8 are each provided with the centrally located and verticalguide-bar 12, and these guide-bars 12, are embraced by the bifurcation13 of the Weights 11. 1

For a suitable distance each side of the center of the press, the middlestrip or bar, of the series forming the front side, is dispensed with,so as to form a longitudinal and horizontal slot 14:, between the middleportion of the upper and lower strips or bars of the said series, andprojecting forwardly through this slot 14, is the bifurcated casting 16,of the plunger 15, which reciprocates to the right and left of thecenter of the press.

Q 17 designates the lever, to which the draftanimal is attached, and therear portion 18 of this lever, comprising a fiat plate or bar, ispivotally connected to the bifurcated casting 16, of -the plunger. Inorder to provide a support for this lever, a segmental guide-plate 19Vis provided,and this segmental guide-plateis bolted or otherwiserigidly `secured i to the front side of the press, and below the portion1S of the lever. Secured to the press at each end of the slot 14, is aneye-bolt 20, and these eye-bolts are pivotally engagedby verticallydepending hooks 22 of the horizontally arranged rods 21. These rods'converge outwardly, and are provided at their outer ends with dependinghooks 24, and these hooks 24.,

pivotally engage apertures 25, formed at equal distances from thelongitudinal center of the lever. These rods 21 perform alternately thefunctions of a movable fulcrum and a guide, as hereinafter explained. 1

In'order that the operation may be free, the

segmental guide 19 is formed at equal dis-v tances each side of itscenter, with the notches or recesses 26, which allow `of the passagetherethrough of the lower ends of the hooks 24, which project below theportion 18 of the lever. If desired,however, these notches or recessesmay be dispensed with, as it is not essential to project the ends of thehooks 24.,

ICO

below the portion 18 of the lever; If desired, also, the hooks upon therods 21 may be dispensed with, and the eye-bolts 20, and any or` dinarypivotal connection may be substituted therefor. This construction isshown because it is about the cheapest and strongest connection that canbe made. In order that the rods 21 may not become disengagedaccidentally at their pivotal points, the plate 26a is secured to theouter side of the press, and slightly above the said rods.

In order to have as little friction as possible, the rear side of theplunger is provided with antifriction rollers 27, which bear against theinner side of the upper and lower strips 'or bars. The plunger is alsomounted upon ya series of antifriction rollers 28, which travel upon thefloor or bottom 2 of the hay press.

In `order to increase or diminish the tension upon the bale beingformed, the frictionplates 29 are provided, and these frictionplates arehinged at their inner ends at 30, adjacent to the outer orhinged ends ofthe doors 7. When the friction-plates 29, occupy Ya 'horizontalposition, they lie in the same plane as the doors 7 when closed. Acasting 31, is secured upon the top 1, of the press, a suitable distancefrom each end, and is provided with a vertical threaded passage, whichis engaged by the threaded portion of a vertical .rod 32. In order thatthese rods 32 may be turned, they are, provided with handlebars 34, attheir upper ends, and are .also provided at their lower ends, whichproject vertically downward into the baling-chambers, with stop-plates35. These stop-plates, however, may be dispensed with if desired.

In the operation of forming a bale, the hay is forced outwardly by theplunger, and coming in contact with the under side of the friction-plate29, causes the same to swing vertically upward, until its limit ofmovement in that direction is reached by contact with the stop-plate 35.It will be seen that this movement may be increased or diminishedV bythe proper manipulation of the adjustable rod 32.

Securedvertically to the front side of the press, at each end, is -acasting 36, and projecting outwardly from each casting, and in the samehorizontal. plane as the slots 5, are cylindrical rods 37.

A spool of wire 3S is mounted rotatably upon each rod 37, and isretained thereon by a nut 39. The wire from these spoolsisvcarried-inwardly and passed through the guideloops or eyes 40 at theinner end of the slots 5. It is thence carried transversely through the-baling chambers, and also through the oppositely disposed slots 5 atthe rear side of..

the machine, and is secured to a pin or other suitable projection. Bythis arrangement an automatic or self feed of the baling-ties isobtained because, as-thehayis forced outward by the plunger to form abale, it first comes inpcontact with the transversely extending portionsof the wire, as shown clearly in Fig. 3, and, forcing the same outward,causes the spools to rotate upon the rods 37 to pay out sufficient wireto form a complete tie.

In the operation of the machine, one of the doors 7 is Vdepressed orclosed, and the operator standing thereon forks the hay through theother opening and in advance of the plunger. As soon as a sufficientquantity of hay is placed therein, and the plunger starts in thedirection of the same, the operator closes the door and steps thereon,leaving the door upon which he previously stood free to be opened by itscounterbalance weight. As the bale is being formed in said chamber thehay is forked through this open door into the opposite chamber. Thisoperation is kept up until the desired number of bales has been formed.

The object in having the doors arranged to close and open thus is toprevent the hay forked into the chamber striking against the opposingshoulder at the outer en d of the feed opening, or against the inner endor shoulder of the corresponding friction-plate 29.

In the operation of the machine it will be seen that the full stroke anda'great leverage are obtained with thel minimum amount of levermovement, because saidv lever-isv provided with a movable fulcrum. Asthe plunger moves towardthe left, it fulcrums upon the hook 24 at theouter end of the-rod 21 `to the right of the lever, and the hook 24 ofthe companion rod 2l, at the left of the lever, performs the functionsimply of a guide, and holds the lever against its fulCrum. vAs theplunger moves to the right, the hook 24 at the outer end of the rod 21,at the left of the lever, becomes the fulcrum, and the'hook 24 of therod to the right becomes the guide. As the plunger moves to the left,the rods 21 pivotally operate in the same direction; and as theplunger-moves to the right the rods 21 also follow the same course.

Because the fulcrumof the lever moves in the same direction as theplunger, it will be apparent that the distance traversed by the levervwill be less than if the fulcrum point were permanently xed.

From the above description, i-t will be seen that I have produced a haypress that issirnple, strong, durable and inexpensive of construction,wherein the power mechanism is directand 'positive in action, andobtains the maximum movement of the plunger lwith the minimum of levermovement.

Having thus described my invention, what I claim. as new, and desire tosecure by Letters Patent, is- Y l. In a hay press, the combinationwith asuitable frame a plunger, and a lever pivotally connected thereto, and asupport for said lever carried by the machine,'of a rod pivot p allyconnected tot-hemachine and pivotally connected to the lever to form afulcrum'for they same, substantially as set forth.

suitable Daling-frame having alongitudinal slot in its front side, a.plunger havinga casting projecting through said slot, and a supoppositesides of its longitudinal center, sub- 1o stantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
